Fault tolerant application execution model in computing grid

Abstract

Performance and availability of resources cannot be guaranteed in the highly distributed and decentralized grid environment. For a reliable application execution in grid, mechanisms are needed to minimize or neutralize the effects of resource related faults and their volunteer leaving or joining the grid. In this paper a fault tolerant application execution model for grid has been investigated. The proposed model is an efficient solution towards resource usage and application execution cost. Analytical study of the reliability for the proposed model is specified. Illustrative examples are also presented.
